Logged In: YES user_id=38376 "Does it tell you more than _just_ that? It doesn't for me." All requests against the file in question were issued by the python process; there's no sign of virus checkers or other external applications. Also, whenever things failed, there were always multiple requests for cmd.exe (caused by os.system) between the WRITE request and the failing OPEN request. My feel, after staring at filemon output, is that this is a problem in the Windows file I/O layer. NTFS queues the various operations, and calling an external process with stuff still in the queue messes up the request scheduling.
